VJATER-CLOSET-FLUSHING DEVICE.

, Application filed November 18, 1925. Serial No. 69,934.

This invention relates to water closet flushing devices and particularly belongs to the class of automatically operated valve mechanisms actuated by the action of the seat, which is slightly lowered when in use and self-raising thereafter.

The principal object of this invention is to place the entire valve adjustment and control within the water box, wherein which the parts are less subjected to being tampered with, are encased and receive the least amount of disturbance.

Another object is to provide a perfect seat of the dushing valve, whereby leakage due to imperfectly seating valves is absolutely eliminated.

A further object is to facilitate and positively fix a predetermined amount of opening to the flushing valve, which will not be subjected to further regulation.

(Ether objects and advantages will be disclosed in the following description and in the accompan ing drawings, in which:

Figure 1 represents the top view of a water box, its cover off to show the general arrangement according to the invention, and

Figure 2 is a front elevation of the same arrangement, the box being sectioned and the front wall taken away.

Similar reference characters similar parts in both views.

This low type of water closet flushing arrangement generally places the water box 1 in proximity to the seat 2, which is pivotrepresent ally mounted to the lower front edge thereof;

One of the supporting members 3 projects rearwardly under the box 1 and an arm 1 is pivotally mounted on the end thereof. An adjusting screw 5 is fixed to the front end of the arm a and abuts against the member 3, for the purpose of adjusting the space of movement between the seat 2 and the closet bowl (not shown). The rear end of the arm 4 abuts under the extending bar 6 of a counterweight 7 that holds the seat 2 in its raised position and controls an upwardly directed rod 8 actuating a lever 9 of the valve opening arrangement.

This flushing valve opening arrangement consists of a cross-piece 10 pivotally mounted at the top of the box 1, between the front and rear walls 11 and 12 respectively, and having its rear end 13 fixed to the lever 9 and having an integral horizontally extending forked arm 1 1 suspending an oscillating hooking member15. This member 15 is somewhat of a cross shape with the lower arm forming a hook 16 having an integral lower wire guide 17 maintained within a semicovered vertically movable casing 18 fitted within a tube 18 integrally mounted upon a bracket 19 fixed to the ordinary overflow pipe 20 of the box 1, and a slot is made vertically along the tube 18 to permit the movement of a closed linger 21 fixed to the casing 18. The flushing valve 22 is vertically directed straight and invariably seated in the same position, by means of an upward square stem 23 guided through a relative sleeve 24 integral with the bracket 19. The stem 23 extends slidably through the finger 21 and a nut 25 is fixed to its end to limit the movement necessary to raise the valve 22 from its seat 26.

The arm 27, of member 15, extends slightly beyond and under the cross-piece 10, against which it contacts so as to cause the hook 16 to freely pass through the semicovered top of the casing 18. On the end of the opposite arm of member 15 is a counterweight 28 that forces the hook 16 to catch under the covered portion of casing 18 when the mechanism is actuated.

Thus, the seat 2 being preadjusted above the bowl, by means ofthe screw 5, is normally held so by the counterweight 7 and this adjustment is relative to the distance between the finger 21 and the nut 25 to raise the valve 22, as well as to the hook 16 lowering inside the casing 18 to catch under the covered portion thereof. When the seat 2 is lowered to the bowl, it raises the counterweight 7 and its arm 6 raises the rod 8 that actuates the lever 9 causing the arm 14 to' lower the member 15 and the hook 16 is guided within the casing 18. Upon raising from the seat 2, the counterweight 7 reverses the motion and the hook 16 raises the casing 18 that moves up the finger 21 until it engages the nut 25 and raises the valve 22 suificiently for the water to flush ordinarily. At that point, the arm 27 contacting against the cross-piece 10 causes the hook 16 to slide off the covered portion of casing 18, which is released and falls in place leaving the valve 22 to reseat itself perfectly.

I am aware that there are other arrangements for automatically flushing water closets and this invention may also be greatly modified without departing from the spirit and scope thereof, so I do not claim this autoi'natie device broadly, but

What I do claim as my invention is:

In combination with a water box, a flushing valve therefor and an actuated mechanism to operate said valve, an automatic arrangement interposed between said niecha nism and said valve comprised of a crossshaped lever having one arm downwardly guided within a semi-covered slidable casing, said lever arm having a hook that engages beneath the semi-covered top of said casing when the said mechanism is partly operated. Said lever having another arm abutting against a part of said actuating mechanism and being adjustable in relation to disengage the said hooking arm from the said slidable casing, said casing being mounted within a slotted tube integral with the overflow pipe for the said valve and means integral with the said tube and the said overflow pipe whereby the stem of the said valve is slidably actuated by a linger integral with the said casing and the said valve being operated thereby substantially as described.
